You can shorten the tests

from graphics import *

def patchdrawer():
    win = GraphWin("Patch drawer", 100, 100)
    for x in range(0, 5):
        for y in range(1, 6):
            p1 = Point(x * 20, (y - 1) * 20)
            p2 = Point((x + 1) * 20, y * 20)
            rectangle = Rectangle(p1, p2)
            rectangle.setFill("red" if (x + y) % 2 else "white")
            rectangle.draw(win)
    for x in range(0, 10):
        for y in range(0, 10):
            centre = Point(((x + 1) * 10) - 5 , ((y + 1) * 10) - 5)
            circle = Circle(centre, 5)
            circle.setFill("white" if (x % 4) // 2 == (y % 4) // 2 else "red")
            circle.draw(win)
    win.getMouse()
    win.close()

if __name__ ==  "__main__":
    patchdrawer()
